if you will use a sub you can go much smaller look my SCHALMEI Sat
Or maybe two tall box subs placed next next to the mains.
Actually my wife doesn't like subs so I would have to find some way of incorporating the sub into the same space or box.

I might still go with the two sub or bass box idea. But my wife says I have to finish all my other projects first. Ahhh, our spouses just don't understand.

I like the Austin. Except for the wider front baffle piece. Does it have to be so?

Defunct! I was going to make some simple TLs with the Fostex FE166Ens. Or are you refering to something else?

If TL/MLTLs are the plan you might look up Bob Brines - he has a nicely sized MLTL for the Fostex FE166EN.

Yes. It ensures a balanced response by ensuring the baffle-step frequency is low enough to be compensated for by the horn.

The FE166E, which the Austin 166 was designed for, is defunct. The current model is the FE166En, which is far from ideal for simple TLs. You can get away with an MLTL, but the FF165wk is somewhat better suited to such loads -I believe Bob shifted to that when it became available.

Maybe I should go with a BLH for the FE166En. MLTL? I forgot what that stands for. Anyway, I think I've seen BLH plans for the FE166En on this forum somewhere.

Question Concerti Clone for the FE163En-S?

Would a Concerti Clone like Leonidas built elsewhere on this forum for the FE166En and FT17H work for the FE163En-S? Or would it need a total redesign (different dimensions etc.) Would it be advantagious to add a T90 super tweeter on top later? (As spouse and budget allow.)

Hey anybody know what has happened with FEASTREX? The only comment I could find on their forum, besides mine, is about a year old.

I hope they're OK. It's my dream to have a set of Feastrex speakers. Sometime in the next 2 years I hope.

MLTL = mass loaded transmission line.

Lots of back-horn plans around for the 166. The 'Concerti clone' isn't really a clone, since the Gemme Audio Concerti was just Fostex's own FE108ESigma horn smoothed out with translam construction, and the Concerti Clone AFAIK does not share any of its dimensions or construction techniques. It would probably need a redesign, although I'd need to check.

Feastrex? Still around TTBOMK, but they relied heavily on Chris Witmer to advertise / promote their products in the West. Since he sadly lost his life in a road accident, they seem to have struggled with communication issues. I don't think they're especially bothered though.
